Cloverleaf Server reboot – not Host server

[Sam Craig]

Previous post might have been misleading, so I am asking again.

How often does your organization reboot the Cloverleaf server?

Here is the paragraph from Cloverleaf Integration Services User Guide, Volume 2 / Version 5.5 / page 433…….

Booting Your Machine

Part of maintenance is booting the Cloverleaf

AIX 5.3, running CL 5.5 Rev1

We reboot only when we have to.  It appears our last reboot was 6/21/09, and I think it was because we had some network or data center maintenance.

AIX 5.3, Cloverleaf 5.5

We only reboot the OS for hardware/software maintenance as required by the action being performed (many of our hardware maintenance items are hot-swap).

[Sam Craig]

Thanks for the responses….

We are also AIX 5.3 and Cloverleaf 5.5 Rev1 and our server has been running for 244 days.

We have a reboot scheduled for tomorrow to apply some AIX maintenance.

As a matter of a routinely schedule reboot….we dont !

[Jerry Tilsley]

Our Linux server which hosts our Cloverleaf hasn’t been rebooted for 322 days, on only then because we added enough interfaces that we finally need to adjust the shared memory parameters!

We have not re-booted our AIX Server for four years and everything is fine.

I would not recommend runnng a Windows Server for more than four days without a reboot, however.

Folks,

We schedule quarterly reboots to exercise our Business Continuity procedure:  we maintain two side by side production servers in our data center and perform a manual failover (takes about 30 minutes).  Also:  at one time in Cloverleaf history, then Quovadx support recommended at least a quarterly reboot to clean up memory – sorta like taking a bath at least every 3 months.  If messages drain we do a complete scrub of all of our sites too (we are multi-site).  The justification back then (from support) was that the engine starts to do “weird” things

if they are not cycled and memory cleared.

This has served us well as our engines continue running fine.

We also are an AIX 5.3R2 TL8 shop.

Enjoy.

Thanks again for all the responses.

More ammo to keep my Cloverleaf application on AIX server and not a Windows server. 8)

Booting weekly for a windows box is not uncommon and likely prudent.

Whoever worte the manual to boot so often might be talking about windows.

I like to try and reboot our AIX boxes once a year because that is how far our backups go.

I ususally have a reason that will allow me to do reboot before 360 days of uptime.

However, I rebooted a PROD box this past year that had been up over 900 days before I got a window of opportunity to reboot.

I don’t know whether to be proud or ashamed.

I was wondering just how long the most uptime anyone had actually done would be and Troy at 4 years beats anything I know of.

Does anyone have more uptime with a cloverleaf box than 4 years?

[Troy Morton]

I was wrong.  Our uptime is actually 917 days.

[Robert Milfajt]

Yeah Troy, big difference between 4 years and just under 2.5 years!   😆

We don’t keep our systems up that long, because I try to replace them every couple of years.

[Robert Milfajt]

Must be nice to have the money to do that…

We reboot Cloverleaf once a month.  It coincides with a regularily scheduled downtime for a software load on our HIS, so users don’t know any different.

[Thomas Fortino]

Running AIX 5.2 Platform V 5.3P_Rev2. We only reboot for hardware maintenace. Our production server’s uptime is 185 days. I cycle the production hostserver and monitor daemons monthly.

[Michael Lacriola]

Same here. AIX 5.3 up for 209 days. Let’s here it for Unix!!! If you windows server is up past 6 weeks, then you are not loading your security patches. We call it Microsoft Tuesday..
